David Rittenhouse

“ Rittenhouse, it must be rationally supposed, was less acquainted with mankind, than General Washington was known to be: he had much fewer and more limited opportunities of studying human nature; and professions of pretended patriots were, therefore, more likely to impose on the unsuspecting honesty of his nature. He may even have been deceived, for a while, and ere the plausible fallacies of theorists in matters of civil polity, emanating from the philosophy of the French school, had yet been manifested to the world. ”

“ Rittenhouse had no claims to what is termed genius; and therefore did not, probably, duly appreciate the early specimens of that talent, which appeared so conspicuous in his son David. Hence, he was for some time opposed to the young man’s earnest desire to renounce agricultural employments; for the purpose of devoting himself, altogether, to philosophical pursuits, in connexion with some such mechanical profession as might best comport with useful objects of natural philosophy, and be most likely, at the same time, to afford him the means of a comfortable subsistence. ”

“ To whatever degree the justness of this observation may extend, it will apply still more forcibly to any country, wherein a disregard, consequently a declension of learning, science and moral virtue, is perceived. Rittenhouse lived in an eventful age. During a long period of his life, he witnessed a comparative simplicity of manners and much integrity of character, among his countrymen. He beheld a progressive course of useful knowledge, and an advance in those arts and refinements of polished society, which minister as well to the rational enjoyments as to the conveniences of human life ”

“ Rittenhouse should have been selected as the President of the Democratic Society, and chosen for that station, can be readily accounted for. This gentleman had evinced, from the commencement of the troubles between the American colonies of Great-Britain and the parent country, an ardent attachment to the cause of his native land. The benevolence of his disposition rendered him the well-wisher of all mankind: hence every thing that, in his view, bore the semblance of oppression, was odious to him. ”

“ The Life of such a man as Rittenhouse could not, therefore, in many respects, be either well comprehended or duly estimated, unless there had been connected with it some account of men and things, to which his private pursuits and public employments were, directly or indirectly, related. ”

“ Rittenhouse—and, consequently, well knew his worth as a man. This representation being likewise made by a person whose conspicuous attainments in similar departments of science, and arduous employments in practical pursuits of the same description, render him eminently qualified to judge of his deceased friend’s talents, he is by these means enabled to form a just estimate of his character. The person here referred to, is Andrew Ellicott, Esq. a gentleman with whom the writer of these Memoirs has been in habits of intimacy and friendship, many years. ”

“ In the year 1787, an handsome edition of the English Book of Common Prayer, with a translation into the Mohawk language by captain Joseph Brant, was published in London.
178. Mr. Rittenhouse is not mentioned in the petition, by name. This was unnecessary: for it was universally known, that it could apply to no other person in America, so unquestionable and pointed are its allusions to him; and that, perhaps, no other Astronomer then living, so well merited the high encomiums on his philosophical abilities, which it contains. ”

“ Rittenhouse had no more faith in the notion entertained by some visionary men, of the attainment of the perfection of virtue, in this life, than he had in the fantastic opinion, maintained also by some, of the perfectibility of human reason. ”

“ At the same time, they exhibit to the world a faithful portrait of a Man, whose character had early acquired the well-earned respect of the wise and good in other nations. During his life, the name of Rittenhouse received due homage from some of the most illustrious Philosophers of Europe. In his own country, that name cannot cease to be venerated, so long as genius, 538science, and virtue, shall be held in the high estimation to which they are entitled. ”

“ But, that an American citizen of slender fortune, one who was (to use the strongly expressive terms of the Philosophical Society, on the occasion just mentioned,) “indebted for bread to his daily toil,”—that a man, thus circumstanced, could be expected to contribute a large portion of his inestimable time, wholly unrewarded, either to the public interests or the acquisition of personal fame, would be an impeachment of his prudence. Dr. Rittenhouse was not gratuitously furnished with a complete Observatory and Astronomical apparatus ”

“ Genius, science, modesty, purity of morals, simplicity of manners, marked him as one of nature’s best samples of 456the perfection she can cover under the human form. Surely no society, till ours, within the same compass of time, [308] ever had to deplore the loss of two such members as Franklin and Rittenhouse.”
In England, the talents of Dr. Rittenhouse were well known, and his worth duly appreciated. Of this, no better evidence can be required, than the spontaneous admission of him, by the Royal Society of London, into a Fellowship of their illustrious body. ”

“ Mary, with John Johnson, the father of Casper, John, Nicholas, William, and Benjamin Johnson, some of whom are now (or were lately) living, in the neighbourhood of Germantown; Catharine, with Jacob Engle, in the same vicinity; and Susanna, with Henry Heiley of Goshehoppen.
William Rittenhouse, the eldest brother of our Philosopher’s father, died at the paper-mills, near Germantown. He left several children, one of whom did lately, and perhaps yet does, carry on those works.—Henry and Matthias removed to the townships of Worcester and Norriton, about the year 1732 or 1733 ”

“ To a system of civil polity, productive of such substantial benefits to all those under its immediate operation, Dr. Rittenhouse would naturally have been inclined: his habits, manners and principles, would so dispose him. Hence, after having indulged, for a moment, the pleasing but fanciful hypothesis, that if the inhabitants of the other planets resemble man in their faculties and affections; if, like him, they were created liable to fall, though some of them might be presumed to retain their original rectitude ”

“ Amidst the more important philosophical pursuits which engaged Mr. Rittenhouse’s attention before his removal to Philadelphia, as well as after he fixed his residence in that city, he now and then relaxed the energy of his mind from its employment in laborious investigations, by bestowing a portion of his time on minor objects in physical science; and indeed, sometimes, even on little matters of ingenuity, curiosity and amusement. ”

“ As an artist he has exhibited as great a proof of mechanical genius, as the world has ever produced. He has not indeed made a world; but he has by imitation approached nearer its Maker, than any man who has lived from the creation to this day.” [289]
Mr. Jefferson retained the highest esteem for Dr. Rittenhouse, during his life; and it is believed this sentiment was mutual. Letters of friendship were occasionally interchanged by them: part of one of the latest of these, is as follows ”

“ That the world possess so few of Dr. Rittenhouse’s philosophical papers, is a matter truly to be regretted: because records extensively promulgated, of the results of his numerous and laborious researches, concerning the most sublime and interesting operations of nature, would, beyond any doubt, have greatly added to the stock of human knowledge. And this regret is enhanced by the reflexion, that if the government of Pennsylvania could have conveniently pursued the plan proposed to them by the Philosophical Society, 472in the year 1775 ”

“ It is, nevertheless, truly astonishing to find an American writer (the late Rev. Mr. Linn,) who, five years after Dr. Rittenhouse’s death, published in Philadelphia, where both resided, a poem entitled, “The Powers of Genius;” but, in which the name of Rittenhouse is not once noticed! And yet that gentleman had not omitted to introduce, in one of his notes, an observation which shews, that an European philosopher, also of sublime genius, was present to his mind’s eye!—“From the exhibitions of American talents,” said Mr. Linn, “I indulge the warmest expectations. ”

“ To follow the plough is not a servile labour: it is an employment worthy of a freeman; and if the person, thus engaged, be a man of native talents, aided by some improvement of mind, scarcely any occupation can afford him greater scope for philosophic reflection.
While, therefore, the reader contemplates the celebrated Rittenhouse, such as he was in his maturer years; and then takes a retrospective view of the embryo-philosopher in the period of his youth, directing the plough on his father’s freehold ”

“ Rittenhouse more out of view for some time, with respect to any public employments. Then, all classes of people appeared to have become Politicians. The interests of Literature were neglected; Science, abstracted from Politics, was little cultivated; and all other considerations were, in general, apparently absorbed in the views which the American people entertained of their public affairs, and in the prosecution of measures, adapted either for the obtaining a redress of the then existing grievances, or to meet the possible contingency of an adverse event. ”

“ We will find, that although, without much learning, man may become useful and respectable, yet that he cannot, without it, become polished, enlightened and great; he cannot ascend to that grade in the scale of his Creator’s works, to which his powers are intended to exalt him. If to this rule, a Franklin, a Rittenhouse, and a Washington present exceptions, they are to regarded as mere exceptions, and therefore do not amount to an infraction of the rule. ”

“ There does not appear to have been, for a long time, any occurrence that could have much disturbed the placid composure of our philosopher’s mind,—until 1762; in which year his sister Anne died, in the twenty-sixth year of her age. She was the wife of Mr. George Shoemaker, a respectable citizen of Philadelphia, and a member of the religious society of Friends. A letter which Mr. Rittenhouse wrote to his brother-in-law Mr. Barton, in October 1762, announcing this event, indicates the keenness of his sensibility on the occasion. Mrs. Shoemaker was a woman of intrinsic worth ”

“ De Saussure very justly observed, “amidst complicated difficulties, from which the most persevering minds might have shrunk without dishonour.”
377. Dr. Rush, in his Eulogium on Rittenhouse, has introduced a short invocation, which aptly applies in this place: it is in these words; “Come, and learn by his example to be good, as well as great. His virtues furnish the most shining models for your imitation; for they were never obscured by a single cloud of weakness or vice.” ”

“ Jeremiah Horrox and William Crabtree, two Englishmen, were the observers of the Transit of Venus of 1639.
111. It was not until the year 1786, that Mr. Rittenhouse built the house at the north-west corner of Arch and (Delaware) Seventh streets, in Philadelphia, where he resided during the remainder of his life: but probably it was some few years earlier that he erected his Observatory, a small but pretty convenient octagonal building, of brick, in the garden adjacent to his dwelling-house. ”

“ Rittenhouse, will be with you on Saturday. The Governor says, the Orrery shall not go: he would rather pay for it, himself. He has ordered a meeting of the Trustees on Tuesday next; and declares it as his opinion, that we ought to have the first Orrery, and not the second,—even if the second should be the best.”
158. The Rev. Dr. Peters wrote thus to Mr. Barton, under the date of March 22, 1771—“Dr. Smith has done wonders in favour of our friend Rittenhouse. His zeal has been very active: he has got enough to pay him for a second orrery; and the assembly has given him 300l. ”

“ Thus was the Norriton Observatory furnished with all the more immediately necessary apparatus, in readiness for the important event which was the main object of these arduous exertions. Much credit was due to Dr. Smith, much to Mr. Lukens and the other gentlemen engaged on this occasion, for the assistance which he, and they, afforded Mr. Rittenhouse. Yet the doctor himself very candidly says—in reporting the proceedings of the Norriton committee to the Philosophical Society,—“other engagements did not permit Mr. Lukens or myself to pay much attention to the necessary preparations ”

“ The state of society in this country, so admirable under many points of view, renders this impossible. We should not be surprised or discouraged at a general 495ignorance of, and an almost universal indifference about the learned languages: but this is not all; the public feeling is not confined to mere apathy: it borders on hostility. Numbers are not wanting, persons even of influence in the community, who industriously proclaim, not simply the utter insignificance, but the pernicious tendency of classical learning ”

“ The present work, however, is far from being intended to satirise any one; its author has no such object in view: for, although he has, in some instances, expressed his disapprobation of certain principles, theories, and even measures, which he believes to be not only repugnant to true science, but destructive of both private and social happiness—he has refrained as far as possible from personal censure;—he would much rather be engaged in the functions of an eulogist, than those of a censor. ”
